The last of your autumn leaves have been raked, but there's one last important chore to do - put your lawn mower to bed. Neglecting to empty the gas tank and perform other end-of-season care can shorten your mower's life considerably, and can lead to costly repairs.

Instructions

Difficulty: Easy

Things You’ll Need:

Penetrating Oil
Gardening Gloves
Motor Oil
Scrub Brushes
Steel Wool

Step1

Empty the fuel tank. The easiest way to do this is simply to start the mower and leave it running until it runs out of gas. Leave it empty until you're ready to use it again next spring.

Step2

Empty the oil tank, if your mower has one.

Step3

Turn the mower on its side. Hose it down to soften dried grass and dirt; use a stick to scrape off any stubborn materials. Scrub with a soft brush and hot, soapy water to remove greasy matter. Rinse, and allow to dry thoroughly.

Step4

Remove any rust by rubbing the affected area vigorously with a small piece of steel wool. (Be sure to wear gloves.)

Step5

Remove the mower blade and either sharpen it yourself or take it to a professional sharpener, usually listed in the yellow pages under "Lawn Mowers - Sharpening and Repair."

Step6

Clean or replace your air filter. These should be changed once or twice during the mowing season. If the filter is paper, replace it. If the filter is made of paper and foam, remove the foam part and wash it in warm, soapy water; let it dry thoroughly. If the filter is plastic foam, remove it and wash it in warm, soapy water; allow it to dry thoroughly; and once it's dry, work a tablespoon or two of clean motor oil evenly across and into the filter - just enough to lightly coat it.

Step7

Refill the mower's oil tank with fresh oil. Leave the gas tank empty until you're ready to use the mower in the spring.

Step8

Check your lawn mower maintenance manual for other suggested season's-end care.

Tips & Warnings

Protect the mower blade from rust and moisture during the winter by giving it a light spray of penetrating oil. (A popular brand name is WD-40.)
Dispose of your old mower oil properly. Never dump it on the ground - or worse yet, in a drain or sewer. Instead, check with local filling stations, many of which collect old motor oil for environmentally correct disposal. If you can't find a station to take it, call your garbage collection service to find out the correct way to dispose of hazardous waste in your area.

on 11/22/2005 Spray the underside of the cutting deck with a penetrating oil to prevent rusting.
It is common for the deck of a lawnmower to rust out before the engine expires.

on 11/22/2005 It is just as important to drain the gas from the gas tank as it is to drain the gas from the carb.
Stored gas in the carb will gum up after about a month and clog the fuel jet that supplies the motor with gas.

on 11/22/2005 It is very important to spray a small amount of lubricant into the combustion chamber by removing the spark plug.
After doing this, replace the spark plug and pull on the starter cord a couple of times very slowly.
This will lubricate the piston rings.
